Abstract
The invention relates to equipment for processing steel reinforced bar threads, which comprises an end part reinforced mechanism, an end surface milling mechanism and a thread rolling mechanism which are sequentially arranged. The end part reinforced mechanism comprises a pull-push mould which is sleeved on a steel reinforced bar end part and can perform axial reciprocating motion along steel reinforced bars, a clamping tool and a drive device; the pull-push mould is formed by a cone pull mould, a supporting seat and an end cover; the cone pull mould is of a frustum cylinder shape; the outer conical surface of the frustum cylinder is of a frustum shape; an inner hole of the frustum cylinder consists of a conical hole, a small circular hole and a large circular hole which can accommodate the steel reinforced bars; and the conical hole and the small circular hole together form a cone pull mould inner hole for extruding the steel reinforced bar end part into a cylinder. The cone pull mould is fixed in the supporting seat and axially fixed by the end cover. The backward push process of the cone pull mould and the rolling thread process both strengthen the steel reinforced bar material; and the tensile strength of the backward push part of a steel reinforced pull mould and the rolling thread part exceeds the tensile strength of steel reinforced bar parent metal by using the cold-work hardening of metal materials.

Background technology
At present, building iron straight thread interconnection technique comprises that mainly the jumping-up straight thread connects, directly the roll extrusion straight thread connects, peel rolled straight thread connects, crowded (stone roller) presses rib roll extrusion straight thread connection etc.; Wherein peel rolled straight thread connects, crowded (stone roller) pressure rib roll extrusion straight thread connects all is earlier the horizontal stroke of reinforcing bar, vertical rib to be carried out the roll extrusion straight thread after anticipating again.
The processing method of screw thread steel is in the peel rolled straight thread interconnection technique: earlier rib is shelled in the end of reinforcing bar, be processed into cylinder, and then rolled thread.Two procedures once machines on the peel rolled straight thread make-up machine, and processing method is simple, and quality of connection is stable, reliable, has now become the mainstream technology that China's reinforcing steel bar machinery connects.Owing in the peel rolled straight thread processing method horizontal stroke of reinforcing bar, vertical rib processing are removed, the bar cross section area is weakened to some extent, when the length that exposes screw thread after the branch sleeve connection is longer, often the disrumpent feelings screw thread position that occurs in of splice stretching exists the lengthening nipple not wait strong problem.
Squeezing (stone roller) presses the screw thread steel processing method of rib roll extrusion straight thread interconnection technique to be: adopt the cylinder mold extruding that has circular arc or roll reinforcing bar the cylinder roller die that has circular arc, the horizontal vertical rib crowded (stone roller) of its end is pressed into cylinder, then rolled thread on cylinder.The intensity of its screw thread improves a lot than ripping rib and rolling depressing, but it usually needs repeatedly crowded (stone roller) pressure could form cylinder in crowded (stone roller) pressure process, complex procedures, and efficient is lower.
Summary of the invention
The invention provides a kind of screw thread steel process equipment and method, solving the spiral strength of joint that extends can not wait strong and the round problem that influences the reinforcing bar quality of connection of crowded (stone roller) pressure rib cylinder, and it is not high to solve the screw thread steel crudy, the technical problem of complex process.
The technical solution adopted for the present invention to solve the technical problems is:

Above-mentioned face milling mechanism can be planar ends milling head or plane and chamfering combination end mill head.
Above-mentioned thread rolling mechanism can be two-wheeled thread rolling or three-wheel thread rolling.
End mechanism for intensifying, face milling mechanism and thread rolling mechanism that said sequence is arranged can divide the station setting on an equipment, also three mechanisms independently can be mounted to equipment respectively, and three equipment are arranged in proper order.
The Screw thread process method of this screw thread steel process equipment,
Above-mentioned milling mechanism can be planar ends milling head or plane and chamfering combination end mill head, and plane and chamfering combination end mill head are to be built-in with rose reamer and plain milling cutter at the milling seat.
Above-mentioned thread rolling mechanism is two-wheeled thread rolling or three-wheel thread rolling.
In the step 4, the screw thread of reinforcing bar cylindrical die roll can be triangle thread, trapezoidal thread or gas thread.
Beneficial effect of the present invention is as follows:
The present invention adopts the cone withdrawing pattern technology of retrodicting earlier, under reinforcing bar maintains static state, the cone withdrawing pattern is forced into end reinforced, utilizes irregular basic circle cylinder of reinforcing bar and horizontal, vertical rib the cone withdrawing pattern to force the metal material distortion, make its mold pressing become cylindrical column; Secondly the cylinder end is carried out face milling and chamfering; On cylindrical column, go out end reinforced straight thread at last by the squeezing thread processes.
Retrodict process and squeezing thread process of cone withdrawing pattern all strengthened the reinforcing bar material, utilize metal material flow harden characteristic to make the retrodict tensile strength of part and squeezing thread part of reinforcing bar withdrawing pattern surpass parent material of reinforcement rebar itself, when the joint test for tensile strength, all break on non-enhanced parent material of reinforcement rebar.For using lengthening spiral joint, higher than peel rolled straight thread bonding strength, it is more convenient to construct.
